The new generation of roof fan is a system for all sizes: it offers high efficiency thanks to the special airflow with low pressure losses. The filter mat replacement is quick and uncomplicated due to the good accessibility. An innovative terminal fixture allows the protection class IP55 as standard. The passive version works without fans with natural convection. The performance range of the active fan is between 500 and 1,000 m³/h.
